neotenic

However, the young man can take advantage of the fact that older men are also of the generation before, who are less neotenic and look more like apes.

Direct-developing and normal biphasic frogs have slightly larger genomes, followed by biphasic, then direct-developing, and finally facultatively and then obligately neotenic salamanders.

Sermonti therefore argues that neotenic organisms - in which juvenile traits persist into adulthood, e.g. gills in adult salamanders - must be archaic, because their features appear earlier in development.
